Because it has two h bridge circuit inside.
L293d motor driver circuit diagram pdf.
It means that you can control two dc motor with a single l293d ic.
L293d is a suitable device to use for stepper motors gear motors etc.
Where to use l293d ic.
A single l293d ic is capable of running two dc motors at the same time.
It can simultaneously control the direction and speed of two dc motors.
The l293d is a popular 16 pin motor driver ic.
However you need to know functions of every pins before it can work better for you.
These ics are designed to control 2 dc motors simultaneously.
It can also drive 2 stepper motors unipolar or bipolar single coil or double coil interleaved or micro stepping.
We will be referring the motor driver ic as l293d only.
L293d is a 16 pin ic which can control a set of two dc motors simultaneously in any direction.
Stepper motor drivers dc motor drivers latching relay drivers.
L293d motor driver chip is used in a wide range in circuits the most common applications.
As the name suggests it is mainly used to drive motors.
L293d is a 16 pin motor driver ic consist of quadruple half h drivers.
L293d equivalent dual timer ic.
L293d consist of two h bridge.
The l293d can drive small and quiet big motors as well.
L293d has 16 pins.
There are various ways of making h bridge motor control circuit such as using.
This motor driver expansion board is based on the l293d chip which is designed to drive up to 4 bidirectional dc motors with individual 8 bit speed selection.
H bridge is the simplest circuit for controlling a low current rated motor.
The most commonly used motor driver ic s are from the l293 series such as l293d l293ne etc.
